JACOB D. BURGER, OF CHICAGO, ILLINOIS, ASSIGNOR TO REISS BROS. & CO., CHICAGO,

ILLINOIS, A ,COPARTNERSHIR PIPE.

Specification of Letters Patent.

Patented Aug, 1, 19,

To all 'whom it may concern.'

Be it known that I, JACOB D. BURGER, a citizenl of the United States of America, and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Pipes, of which t-he following is a specification.

My invention relates to pipes inv general, but more particularly to those in .which the bitis made detachable from the bowl by means of a smooth push that enters the stump of the bowl to connect' the two parts of the pipe rigidly together. Ordinarily the bit and the push are made integral, while in other1 instances the pushis a separate piece fastened rigidly into the bit; but in all cases, heretofore, the push has been breakable as compared with the bowl stump andthe bit, being made ordinarily of rubberl or bone. As is well known, the weakestpoint in a pipe of this type lies at the juncture of the bit and the bowl stump, and consequentlyatthis point the .pipe stem frequently breaks, leaving the screw or push extension fixed in the stump and rendering the bit useless. Thisbreaking occurs more frequently when the pipe is carried in the pocket of the user, and by reason of this fact many users of pipes carry them in a protecting case, this belng especially the fact with high priced pipes. Moreover rubber and bone, the materials most commonly regarded as Vproper for the push or screw, are subj ect to deterioration and have occasioned considerable trouble by swelling or shrinking or cracking when subjected to the action of heat and smoke and saliva. No real attempt, in my judgment, has heretofore been made to avoid this'defect, and apparently pipeinventors and manufacturers have the world over considered` this to be a defect inherent in this type of pipe. In other words, this defect has been apparent-ly accepted by the trade as an unavoidable evil or drawback of this type of pipe.

My invention contemplates, therefore, the provision of means for connecting the bit of a smoking pipe to the bowl stump thereof in such manner that breakage of the connection, for example the push, will be practically impossible, and whereby, at the saine time, the saidA -push and other parts will withstand without injury thereto, or ill effects on the smoker, the heat as well as the action of the smoke and liquid result-ing lous chemical substances.

tion made of this metal.

from the use of the pipe, as will hereinafter more fully appear.

In the accompanying drawing-Figure 1 is a side elevation of a pipe embodying the most desirable form of my invention; Fig.

2 a cross sect-ion on the line 2-f2 of Fig. 1;

and Fig. 3 a longitudinal lsection of the pipe.

Fig, 4 1s a perspective of the so called push j that connects the stump of the pipe with the bit or mouth piece.

As thus illustrated the bowl A and its stulnp a may be of any suit-able or, well known and 4approved material, the stump being provided with the usual metal ferrule a', and with the usual bore a2 connected by a duct a3 with the chamber a4 of the bowl..

The bit B is of the usual form and is provided with the usual duct b that terminates in the threaded bore b. This bit may be made of rubber, amber, ivory, celluloid,-

horn or any of the well known materials.

The push C has a reduced threaded portion c that screws into the threaded bore b of the bit, while the body c of the push is adapted to be inserted in the smooth bore a2 of the stump. This push is made of aluminum, this metal beingdesirable not only because it is non-breakable in character as compared -with the bit and stump, but

also because it resiststhe action of the smokeJ and saliva, or pipe-liquid, that inevitably collects in the plpe stem during the smoking of the pipe. This metal, therefore, is not affected by the pipe-liquid, is always clean, and-does not corrode or form injuri- Another feature of importance is that the heat of the pipe while in use does not expand it sufficiently to crack the stump, or to bind it in the stump, or to crack the bit.

I have discovered that a push made of aluminum does not deteriorate in any manner whatsoever, does not wear or cut the non-metallic substance of the stump such as wood, and does not possess any of the 0b- -jectionable qualities inherent in the matecretions do adhere thereto, and thus thel joint is kept tight and lirm Without preventing easy separation thereof. l#Vith my invention the push becomes the strongest part of the pipe, and is non-racturable, Whereas previously it Was made weaker than 'the other parts by the use of materials that were brittle and short lived. The aluminum, l

have discovered, not only is not susceptible to attack by the smoke and saliva, and the other resulting chemical substances, but does not acquire any growth by accretion oit foreign matter. lt is practically self cleaning, as nothingproduced by smoking ivill adhere toitssurtace, and for this reason the push will not stick in thestump, but will always come away clean and bright. There .are some things that vvill attack and dissolve aluminum, and the peculiar transparent onid that terms on the-surface thereof, but l have discovered that tobacco smoke can be taken through a duct formed in aluminum with entire safety to lthe smoker.L ln this Way l am the rst to discover and success- .fully demonstrate the possibility of using metal for this purpose and thereby rendering the push much the strongest part ot `the pipe and practically indestructible. l am also the irst, so it would seem, to discover and demonstrate the possibility of using a metal push Without impairing the nonmetallic stump and. bit, and Without endaneoaeae gering` the operativeness of the separable connection. l'have discovered that in one sense an aluminum meta-l is insensible to the emanations from the tobacco. lt prevents caking of the secretions on the push, and

maintains at all times a perfect joint,-that is to say, a joint which is never too 'tight and never too loose.

By the term aluminum, as herein employed, l mean any metal that contains aluminum in sucient quantity to give it the described characteristics and advantages.

1What I claim as my invention is l. In a smoking pipe, a bowl having a-` non-metallic stump, a non-metallic bit, and an aluminum metal push 'forming a connection between said stump and bit, the outer end of said push being fastened rigidly in the adjacent end of the bit, and the inner end thereof being adapted to rictionally enter a smooth bore in the stump, 'whereby the non-metallic substance of the stump is indirect sliding contact with the aluminum, 'the said push having a duct through which 'the smoke passes in direct contact with the aluminum, for the purpose set forth.

2. A smoking pipe having a stump and a bit of non-metallic substance, and an internal aluminum metal connection between saidy stump and bit, atording ready disconnec tion thereof, by relative movement of the aluminum and non-metallic substance in dt `rect Contact With each other, for the purpose set forth.
